Struct rustc_incremental::persist::dirty_clean::DirtyCleanVisitor

pub struct DirtyCleanVisitor<'tcx> {
    tcx: TyCtxt<'tcx>,
    checked_attrs: FxHashSet<AttrId>,
}

Fields

tcx: TyCtxt<'tcx>

checked_attrs: FxHashSet<AttrId>

Implementations

impl<'tcx> DirtyCleanVisitor<'tcx>

fn assertion_maybe(
    &mut self,
    item_id: LocalDefId,
    attr: &Attribute
) -> Option<Assertion>

Possibly “deserialize” the attribute into a clean/dirty assertion

fn assertion_auto(&mut self, item_id: LocalDefId, attr: &Attribute) -> Assertion

Gets the “auto” assertion on pre-validated attr, along with the except labels.

fn except(&self, attr: &Attribute) -> FxHashSet<String>

except= attribute value

fn auto_labels(
    &mut self,
    item_id: LocalDefId,
    attr: &Attribute
) -> (&'static str, FxHashSet<String>)

Return all DepNode labels that should be asserted for this item. index=0 is the “name” used for error messages

fn resolve_labels(
    &self,
    item: &NestedMetaItem,
    value: Symbol
) -> FxHashSet<String>

fn dep_node_str(&self, dep_node: &DepNode) -> String

fn assert_dirty(&self, item_span: Span, dep_node: DepNode)

fn assert_clean(&self, item_span: Span, dep_node: DepNode)

fn check_item(&mut self, item_id: LocalDefId, item_span: Span)

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
